A bike wheel has 6 main parts: the hub (center axle), spokes (typically 24-32 per wheel), nipples (small threaded pieces connecting spokes to rim), rim (outer ring), tire/tube (or tubeless setup), and skewer or thru-axle (mounts wheel to frame). Below, we explain every component and how they work together. All the parts of a bike … Read more
The bicycle freehub is the mechanism that allows the rear wheel to turn freely when the pedals are not being engaged.
Located in the hub of the rear wheel, the freehub is what allows you to “coast” on a bike, meaning the wheels can keep turning while the pedals remain still.
A wheelset is one of the integral parts of a bicycle, and, as the name suggests, contains the system of the wheels.

SRAM XDR and SRAM XD drivers are a type of freehub standard made by SRAM that is compatible with a range of hubs and cassettes.
But what’s different about the SRAM XD vs XDR drivers? And what cassettes and hubs are they compatible with?
Freewheel? Cassette? Freehub? Ever heard of them?
They’re vital components on a bike. So if you don’t know (or want to learn more) you’re in the right place!
On any bike, there is a set of multiple sprockets that attaches to the hub on the rear wheel. The rear cogs consist of one of two different systems: freewheel vs cassette.
